Great customer service. Jim is super helpful and kind! They always give us discounts and don’t try to sell us on stuff we don’t need. When I bring my toddler in and we are waiting for our service to be done— they always put a movie on for him, offer crayons or snacks. Super great, glad we started getting our services here.

Ultimate European Repair

Would like to see more transparency with their invoice breaking out the labor rate and hours to do the job and the cost of parts separately so their costs can be compared to other shops And dealership.
